- One way to measure the slew-rate limitation of an op amp is to apply a sine wave (or square wave) as the input to an amplifier and then increase the frequency until the output waveform becomes triangular. Suppose that a 1-MHz input signal produces a triangular output waveform having a peak-to-peak amplitude of 4 V. Determine the slew rate of the op amp.arrow_forwardEQUATION OF OUTPUT VOLTAGE( NEED ONLY HANDWRITTEN SOLUTION PLEASE OTHERWISE DOWNVOTE).arrow_forwardWhat is the function of a filter?
